Recently I bought a pair of Topcon Hiper GA's on eBay. Yeah, I know they are ancient but so am I. I got them cheap and they should do what I need them to do.
Sometimes when I try to get them initialized everything works fine, but sometimes I can't get the radios to connect. When this happens it doesn't matter which data collector I'm using. I can connect with each receiver using bluetooth but the radios would not connect, no matter how I configured the data collectors.
I finally hooked the base receiver to Topcon Receiver Utility and noticed that under "Positioning" it was set to Standalone. I checked the rover and it was set to RTK Fixed, so I set the base to RTK Fixed and took them outside to try again. They worked with either data collector on the first try. Since then, on at least two occasions I have not been able to get a radio connection and each time I found that the base was again set to Standalone. Today I connected the base to my PC and it was on Standalone again. I changed it to RTK Fixed , disconnected, turned the receiver off, turned it back on and reconnected. Again it was on Standalone.
Is the base receiver positioning mode supposed to be set to RTK Fixed or Standalone? Does anyone have any idea about why it would change modes without being connected to a PC or data collector?
By the way, when I do get them to connect, they work very well for hours.
